The creation of a clash free, error free design will still
leave a project open to considerable risk unless the fabricated parts match the
design intent. If newly fabricated components do not fit, ongoing work may be
delayed and rework may be required. Using laser scanning, Quest Integrity can
identify fabrication errors, allowing variations from design to be easily
detected and visualized.
In a fabrication verification process, spool pieces are
scanned in the fabrication or laydown yards. They are compared to the design
intent to be sure that they will fit properly. Blunders and missing connections
can be quickly found and efficiently addressed before the parts are shipped.
Quest Integrity can provide reports which verify individual
spool pieces or entire lines. Flange center, bolt rotation, flange skew and
critical design lengths can all be identified. Moreover, a full set of
fabricated spools, valves, fittings and gaskets can be shown to mount together
and fit within the assembly tolerances of the tie point coordinates.
This fabrication verification process is extremely valuable
during refinery turnarounds, offshore platforms and is becoming commonly used
in other onshore facilities as well. By verifying fabricated items match
design, our clients have been able to reduce field fit-up welds and eliminate
fabrication clashes saving time and money.
